WINDOW SCREEN.

Application led January 22, 1926.

This invention relates to window screens, and the primary object of the same is to provide a. device of this class constructed for application to the outer side of a window frame and extending the full length of the latter and involving features which insure a tight fitting of the screen frame relatively to the window frame and blind stops, thus producing a sealed joint that will eX- clude moisture and render the screen generally more effective.

The present improvement in screens embodies some of the features disclosed by my pending application Serial No. 2.380. tiled Jan. 14, 1925, allowed Sept. 14, 1925, Patent No. 1,572,786,1feb. 9, 1926.

The invention consists in the construction and arrangement of the several parts which will be more fully hereinafter described and claimed.

In the drawing:

Fig. 1 is an elevation of the outside of a window frame and sash, showing the improved screen applied thereto.

Fig. 2 is an enlarged transverse vertical section through the window frame and sash and the improved screen, showing the latter prior to drawing the same completely closed and fastening it.

Fig. 3 is a view similar to Fig. 2, showing the improved screen closed and fastened.

Fig. 4 is an edge elevation of the improved screen broken through the center and illustrated on an enlarged scale.

Fig. 5 is a horizontal section on the line 5 5, Fig. 1.

The numeral 5 designates a window frame of usual construction. comprising blind stops 6 and a blind stop casing 7, and also a lintel or head member 8 and sill 9. Vithin this frame window sash 10 and 11 are mounted and have the usual meeting rails 12 and 13. The improved screen comprises a frame made up of side strips 14 and upper and lower connecting strips 15 and 1G. At an intermediate point a strengthening bar or strip 17 is interposed at the center of the screen frame and secured to the side strips 14. this center bar or strip 17 being adapted to aline with the meeting rails 12 and 13 of the sash 1() and 11 when the screen is closed and secured. A wire gauze covering 1S is applied over and secured against the outer side of the screen frame, and the preferred means for securing this wire gauze in place consists of longitudinal channeled Serial No. 83,120.

metal strips 19 intersected by upper, lower and intermediate similarly channeled metal. strips 20. 21 and 22, which are preferably held in secured position by removable fastenings such as screws, these strips alongr the sides and at the upper and lower portions of the screen frame, or the strips 2t), 21 and 22, covering the side of the upper and lower edges of the wire gauze and having the flanges thereof projected outwardly. By channeling and Hanging all of the strips as just specified, metal of a comparatively thin character may be used and yet give sufficient strength and durability to the said gauze securing strips to serve the function for which they are adapted. The side strips 19 are of greater width than the side strips 14 of the screen frame and therefore are caused to project outwardly beyond the said 7 screen side strips and bear-against and form a tight joint with the outer portion of the window frame or the blind stop casing, and likewise. the upper strip 2t) is projected upwardly beyond the lower edge of the top structure of the window frame. At the bot'- tom of the lower channeled strip 21 an inwardly and upwardly bent metallic closure strip 23 is secured and adapted to engage the upper outwardly and downwardly inclined surface 24 of the sill 9, the said in wardly and upwardly inclined closure strip 23 being of such shape as to conform to the angular surface of the sill and tightly close the joint at this point between the lower portion of the screen frame` and the said sill.

In the construction of the. screen frame the side strips 11 are longitudinally curved to a slight degree, it being possible to accomplish this normal curvature b v various means. The degree of curvature is about onefourth of an inch in tive feet. and this curvature is indicated by relatively to the straight dotted line 26 as shown by Fig. 2. One simple method of obtaining this curvature is to apply the wire gauze to the front side of the screen frame so tight as to draw the latter and effect the desired curvature of the side strips 14. However, this curvature may be produced by various means, as above noted. and when the screen is hung, the side frame members or strips 14 will have the curvature just specified. The upper end of the screen frame has hangers 27 secured bthereto and movably caught over hooks 28 fixed to the up-part of the window frame structure, as clearly shown by F ig. 1. The hangers are detachable from the hooks 28 so that the outside screen may be removed and applied as desired. At the opposite sides of the central portion of the lower part of the screen frame fastening devices, preferably in the form of hooks 2l), are secured for engagement with eyes 8() projecting upwardly from the opposite sides of the renier ot' the sill J at a suitable distance inwardly, to permit the screen frame to be tightly drawn into plaie and secured.

After the improved screen has been hung against the outer side of the window frame, it may be tightly closed by drawing the lower end thereof inwardly and securing the hooks 2) in the eyes 3 The forward pressure or drawing Jforce exerted on the lower end of the screen will cause thc side members or strips 1l to straighten out and rest firmly against the blind stops 6, thus forming a tight or sealed joint. Vvhen the lower end of the screen frame is released7 the side strips 1-1 of the screen frame will again resume their normal longitudinally curved contour. Owing to the comparatively small d mensions of the strips 14 and the length of the latter, the said strips will have more or less of a yielding action and bend or straighten out as just explained. The nietal strips 19 follow the normal curved contour of the frame strips 14 and also straighten out with the said strips 14 when the screen is closed and secured. Owing to the slight curvature of the strips 14 as heretofore explained, the strips 19 will not strain and loosen the fastening means therefor but will regularly yield with the said strips 141-. The projection of the channeled strips 19 and Q0 as heretofore specified also seals the joint creviees between the side and top strips of the screen frame and the portions of the window frame engaged or overlapped thereby, and the lower angulaistrip will likewse form a tight seal with relation to the sill. By this means all of the joint crevices will be closed and inserts and moisture excluded at all times.

Vl'hat is claimed as new is:

The combination in a window screen, adapted to extend full length of the outer s de of a window frame and be movably suspended at its upper extremity from the frame, a wood screen frame covered on the outside with Wire ganze which is drawn taut and secured at its edges to the wood of the screen frame to effect a longitudinal curvature of the latter frame, channeled metal strips fixed in all directions over the side, top and bottom edges of the gauze, said strips eiitending over and beyond the side and uppei edge of and applied to the outer side of the screen trame and adapted to cover the jo'nts between the screen frame and window frame when the screen fran'ie is closed, an upwardly and forwardly inclined metal strip extending below and secured to the lower edge of the screen frame and adapted to engage the sill of the window frame and having a yieldingaction, and fastening means at the lower extremity of the screen frame. In testnnony whereof I have. hereunto set my hand.
